CASH-CARRIER.

Figure 1 a side view of a cash carrier constructed in accordance with my invention. Fig. 2 a sectional view of the operating springs enlarged. Fig. 3 a broken view showing the engagement of the spring 7 with the rod Fig. 4 a sectional view on the line o-b of Fig. 2. Fig. 5 a broken view showing the connection of the spring 7 with the nut 8.

This invention relates to an improvement in cash carriers, and particularly to that class in which a tapered recoil spring is em ployed onto which the car runs, and which spring is employed to impart the power to throw the car from one station to another, the object of the invention being a simple means for mounting the spring whereby it is firmly connected with the track wire; and the invention consists in the construction hereinafter described and particularly pointed out in the claims.

In carrying out my invention a clip 2 is clamped to the track wire 3. This clip is made in two parts which are clamped to the wire 3 by screws 4. Into this clip is threaded a front rod 5 which extends rearward into engagement with the rear pulley case 6. Surrounding the rod and secured to it is a coil spring 7 which spring engages with a collar 8. Surrounding this spring is a long sleeve 9 the inner end of which engages with the collar and enters the catch case 10 in which it is locked by a transverse screw or pin 11 the tendency of the spring being to draw the catch case forward. Surrounding this sleeve 9 is a recoil spring 12. This spring is tapered at its forward end to engage with a tapered inside nut 13 fixed to the rod 5. Beyond the nut the spring continues forward surrounding a sleeve 14 on the rod 5, and the convolutions of the coils are separated for the purpose as will herein- Specification of Letters Patent.

after appear and the forward end enters a buffer nut 15 which is threaded onto the front rod 5 and bears against the front tip 2. On the spring at the rear end is the usual rubber bumper 16. Mounted in the catch case is a catch hook 17, and between the case and the rear end 18 of the hook is a catch spring 19, the tendency of which is to raise the nose of the hook.

As in the usual construction the track wire 3 is wound upon a ratchet 21 secured to a depending post 22 and to which post the rear pulley case 6 is also connected. A handle 23 is connected to a cord 24 which passes over the pulley 25 in the rear pulley case, thence over the pulley 26 at the rear end of the catch case and rearward into engagement with the rear pulley case, and so that downward movement of the handle will draw the catch case rearward. The nose 21 of the catch is adapted to engage with one end of a car 27 which is of usual construction and adapted to ride upon the track wire 3. As the car approaches the station it rides on the coil 12 expanding the coil so as to gradually retard the car yet permit the car to pass rearward until its rear end engages with the hook 20. Vlhen it is desired to throw the car the handle 23 is pulled down, which draws the catch case rearward and with it the car 27, elongating the spring 12. At a predeter mined point on the rod 5 is a trip 28 against which the rear end of the catch engages so as to depress the hook 20 and release the car. This also releases the spring 12, which, shooting forward, gives sufficient impetus to the car to throw it to the station at the opposite end of the track. By loosely coiling the forward end of the spring 12 greater flexibility is given to this spring so that it will yield more readily as the car passes upon the tapered coil so as to relieve the in that direction, and also acts when the spring is released to prevent a sudden jar as the spring contracts. In other words, these small and widely arranged convolutions of the spring at the forward end of the coil act as a buffer for the spring itself. As in previous constructions the spring 7 moves the catch case forward when the handle is released, the sleeve 9 extending between the two springs mounted on the rod.

I claim 1. A cash carrier comprising a track wire, a tip secured thereto, a rod mounted in said tip and extending rearward, a tapered nut on said rod, a coil spring tapered near its forward end to engage with said nut and extending forward beyond the nut, the forward extension being of smaller diameter than the main portion of the spring and loosely coiled, substantially as described.

In a cash carrier, the combination with the track wire, a tip secured thereto, a forward rod connected with said tip and extending rearward to a stationary support, a catch case mounted on said rod, a spring connected with said nut and extending into engagement vdth said catch case, a sleeve surrounding said spring, a throw spring surrounding said sleeve tapered at its forward end to engage with said nut, the forward end of the l I i throw-spring beyond said nut of smaller diameter than the main portion of the spring,

and loosely coiled, a buffer on said throw- 2o spring, a car adapted to ride on the track wire and engage with said throw spring, a catch mounted in the catch case and adapted to engage with said car, and means for drawing the car rearward and releasing it whereby 2 it is thrown forward by said throw-spring, substantiallyras described.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
